Gas burner

ABSTRACT

The open intake end of the gas burner body is contoured for arcuate abutting engagement of not more than 180* with the supply manifold. A pin extends upwardly from the manifold into a slot formed in the upper side of the burner end and extending in a direction transversely of the manifold. The pin and slot, in conjunction with the arcuate engagement, provide the sole means to position and maintain the burner in accurate registration with the manifold orifice. Upon partial rotation of the burner about the manifold, it may be manually removed from the manifold.

Conventionally burner bodies are supported at least in part bysupporting members built into the appliances in which the burners aremounted. There have been instances in which burners have been mounted onand supported by the gas-supplying manifold. However, in such cases theburners have been attached to the manifold by screws or other fasteningmeans requiring the use of tools to mount and remove the burners fromthe manifolds.

SUMMARY OF THE INVENTION This invention has as an object a particularlysimple structure economical to manufacture and by which a burner body isquickly and conveniently attached to a gas supply manifold and removedtherefrom by manual manipulation only, without the use of tools orfastening means. Due to the structure embodied in the invention, theburner body is automatically located and maintained in exactregistration with the orifice in the manifold.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view in perspective of aburner structure embodying our invention;

FIG. 2 is an enlarged coplanar view of the upper right portion of thestructure shown in FIG. 1;

' FIG. 3 is a side elevational view with parts broken away of theshowing in FIG. 2; and

FIG. 4 is a view similar to FIG. 3 with parts broken away showing theburner body rotated a about the manifold for manual removal therefrom.

DESCRIPTION OF THE PREFERRED EMBODIMENT The burner structure includes abody having an open end portion 11 connected to an elongated main burner0 portion 12 by a venturi section 13. The upper surface of the mainsection 12 is formed with a plurality of flame openings 14.

A manifold 17 of cylindrical cross section is provided with an orifice20 in the side wall thereof. The open end of the body is of concaveform, on a radius comparable to the manifold, to provide arcuateabutting engagement with the peripheral surface of the manifold, seeFIG. 3. The burner body shown is in the form of a pair of matingsections formed of sheet metal. The open end portion 11 of the burnerbody includes an upper side portion 23 and a lower side portion 24.These upper and lower side portions are formed to provide for thearcuate abutting engagement with the manifold 17, this engagement doesnot exceed 180. As shown, the upper portion 23 includes an area 25extending tangentially from the upper surface of the manifold 17.

The upper side portion 23 of the open end of the burner body is formedwith a slot 27 located in alignment with the axis of the burner body,and serves receive a'pin 30 fixed to the manifold and extending upwardlyfrom the upper surface thereof. The slot 27 is formed so, uponengagement of the outer end of the slot with the pin 30, the burner isdisposed horizontally from the manifold, and is held in abuttingengagement therewith as shown in FIG. 3. The slot 27 extends in adirection transversely of the manifold and is of sufficient length topermit the manifold be rotated in a clockwise direction about themanifold from the position shown in FIG. 3 to the position shown in FIG.4. Upon movement of the burner to the position shown in FIG. 4, theburner body may be moved radially outwardly from the manifold forseparation therefrom.

The upper and lower portions 23, 24 of the burner end portion 11 areformed with openings for the admission of primary air into the burner.The upper side 23 of the end portion is formed with a rectangularopening 37 of substantial dimension and the lower portion 24 is formedwith an openin 40. The slot 27 communicates with the primary air opening37 in the upper side 23 of the burner body and accordingly the opening37 serves as an extension of the slot.

The burner body is mounted on the manifold by placing the open end ofthe burner body over the pin 30 with the burner body inclining upwardlyfrom the manifold as shown in FIG. 4. The burner body is then moved to ahorizontal position, as shown in FIG. 3, for engagement between the pin30 and the outer end of the slot 27. Accordingly, the pin and slotarrangement maintains the burner body 10 in horizontal position. It alsoserves to locate the burner axially on the manifold whereby the burneris located and is maintained in accurate registration with the orifice20. It will be observed that the burner body is attached to, and alsoremoved from the manifold by simple manual manipulation, without the useof any tools or fastening members.

The structure described, in addition to providing thesole means forattaching the burner body to the manifold, also forms the sole means forsupporting the burner body. Accordingly, the appliance in which theburner is used need not include any burner-supporting structure.

While we have described a preferred embodiment of the invention, it isto be understood the invention is not limited thereto since it may beotherwise embodied within the scope of the following claims.

We claim:

1. An atmospheric gas burner structure comprising a horizontallydisposed gas supply manifold of circular cross section and having anorifice in the side wall, a horizontally disposed burner body having anopen end portion abutting the manifold in registration with said orificeand extending radially frorn said manifold, said open end portion beingof concave formation having arcuate engagement of not to exceed 180 withthe peripheral surface of said manifold, said open end portion beingformed with an opening for the admission of primary air to said burnerbody, the upper side of said end portion being formed with an elongatedpin receiving slot extending in a direction axially of said burner andtransversely of said manifold, a pin fixed to said manifold andextending upwardly from the upper surface thereof through said slot inengagement with one end thereof, said pin and slot in conjunction withsaid arcuate abutting engagement between the burner body and saidmanifold forming the sole means for locating and maintaining said burnerbody in registration with said orifree, all whereby upon rotation ofsaid burner body about the axis of, said manifold to move the oppositeend of said slot toward said pin, said burner body is removable fromsaid manifold by manual manipulation.
